Dora has $35 saved. She earns $9.50 per hour at her job. How many hours must she work to have a total of $358 in her savings?

Subtract the existing savings from the desired savings to see what we have left:
358 - 35 = 323

Now, at 9.50 per hour, how many hours of work does she need to get 323?

Let h be the number of hours. We have:
9.50h = 323

Running this problem through our search engine, we get
h = 34
